How about rounding to:
($987,654,321.70)?
Did you have a look into (require (planet "fmt.rkt" ("joskoot"
"planet-fmt.plt" 1 9)))
Documentation is on planet as an msword .doc file.
I know I should scribble it, but I am not a handy scribbler.
Apart from several numerical formats, it also provides tabulation and
alignment such as to put numbers nicely aligned in the columns of a table.

Subject: [racket] number formatting
How to format numbers prettily, such as for financial work, has come up
a few times before.
I finally released a number formatting library that I've been using for
many years. If you use it, be sure to pay attention to the warnings in
the documentation.
